In whom also believing, you were sealed with the Holy Spirit of promise.

Jesus answered and said to him, You do not know what I do now, but you shall know hereafter. 

Not by might, nor by power, but by my spirit, saith the LORD of hosts.

[Remember your Creator earnestly now] before the silver cord [of life] is snapped apart, or the golden bowl is broken, or the pitcher is broken at the fountain, or the wheel broken at the cistern [and the whole circulatory system of the blood ceases to function]; 
Then shall the dust [out of which God made man's body] return to the earth as it was, and the spirit shall return to God Who gave it. 

If we ask anything according to his will, he hears us.  And if we know that he hears us in whatever we ask, we know that we have the requests that we have asked from him.
